I don’t think I’ve ever done an eye exam with this type of tree chart (they always use slides with rows of 4 letters at my optician), but I still love these tights from Nylon Journal. They’re $27 and come in black on white or white on black.
Their barcode tights are also quite geeky, but I wonder how many people would try to “scan” you if you’d wear these ($24):
The last pair that I really like are these New York subway tights ($44):
I just wish they’d be for the London Underground! Hmmmm, I wonder if those maybe exist already? *goes off to google* Pillows, yes. Aprons, yes. Quilt, yes. But no tights it seems…
